18 Claims. (01. 296-48) which are slidably engaged by the sides of the window. Itis also customary to raise and low-- er the window by means of a single point suspension oif-center window regulator. A common form of regulator used is the stamped metal gear sector type having a lift arm carrying a stud which engages a slotted bracket fixed to the lower windowsash. The point of suspension, that is, the point where th'stud mounted on the regulator arm engages the sash bracket, is usually offset from the center of the lower edge of the window glass at the greater portion of its travel. Hence, in the course of raising the window the lifting force is applied to one side of the center of the lower edge of the window glass tending to make the window cock in the window guides. This tendency of the window to cock in the guides is usually not sufficient to cause the window to lock where the window travels in a true vertical up and down path, but it does have a tendency to make the window slide somewhat harder. Where the window travels in guides which are inclined relatively to the vertical requiring the window to travel in a slanting up and down path rather than in a true vertical path, this off-center lift tends to cook the window sumciently so that it will bind somewhat more in the window guides and make the raising of the window more diflicult. Then again the felt lined guide channels are not always in true parallelism, consequently one or the other of the vertical edges of the glass will particularly at the upper corner, to dig into the guide channel.

It is an object of this invention to obviate this tendency ofthe window to cook when an off-center lifting force is applied thereto, and

vice which at all times holds the Window rigidly in a straight path whether the path be truly vertical or slanting. More specifically the device comprises a channel member positioned in the window well and a traveler rigidly fixed to the lower window sash which has an accurate engagement in the channel guide to thereby determine the rectilinear path traveled by the window. 5

It is a further object of this invention to produce a window assembly in which the glass runways contact with the window only along the inner and outer faces and in which the window is guided in a straight line path during its opening and closing movement by guide means positioned below the belt.

It, is an object ,of this invention to produce a window guide device which can be inserted into the window well from the belt as a unit.

In vehicles of the convertible type the window glass is usually guided entirely below the belt. The guiding device usually takes the form of sash-extensions fixed to the lower window sash which travel in channel runways positioned in the window well. Of necessity to permit the window to be lowered as far as possible into the window well, these sash guide extensions are fairly short and hence do not hold the window very rigidly when it is in raised position. In a convertible body the window is usually not guided above the belt but merely suitably weather-stripped along'the inner face.

It is an object of this invention to produce a window assembly in which the window is rigidly guided and supported against cocking movement within its normal plane as well as against movement in and out its normal plane by guide meanspositioned below the belt rail.

It is. an object of this invention to produce a window assembly in which the window is both adjusted'and gui ed on a straight line path by means positioned elow the belt within the window well.

It is an object of this invention to produce a window assembly in which the window is both guided and adjusted in a rectilinear path by means positioned within the window well and in which the window is detachable from the guide and window lift means at the belt.

It is a further object of this invention to produce a window assembly in which the window is regulated and guided in a straight line path by means positioned within the window well and in which a single plate serves both as a support for the window to give the same a straight line motion and as a guide for operatively connecting the window regulator and the window.

Figure 21 shows a sectional view of a door having a slotted pillar for assemblying the window to the guide device on the form shown in Figures 14 to 17.

Referring more particularly to the drawings there is shown a window well 1 into which the window 2 retreats when it is lowered. The window is arranged to be guided in its movement by a pair of spaced parallel guide channels 3. These channels engage the sides of the window and may be lined with any suitable cushioning material such asv felt. Although the window guide channels 3 are shown inclined relative to the vertical, it is understood that the invention is applicable to a window guidedeither by vertical or inclined window guide channels. The window 2 has mounted on the lower edge thereof the window sash channel 4 which carries a sash bracket 5 having a slot 6. The window is adapted to be raised and lowered by a window regulator comprising a stamped gear sector 7 having a lifting arm 8 with a stud 9 that slidably engages the slot 6 of the sash bracket 5. It will be noted that the stud 9 engages the sash bracket at a point offset from the center of the lower edge of the window glass. The window regulator is mounted upon the lock board 10.

Inasmuch as the lifting force for raising the window is applied to the window through the stud 9 at a point offset from the center of the lower edge of the window glass there will be a tendency for the window to turn in the guides 3 causing the same to cock and bind within the guides. Hence, to obviate this difiiculty, the window is provided with a guide device which determines the course so that it will not bind in the window guides. The window guide device takes the form of a triangular plate 11 having the flange 12. The triangular plate 11 has spot welded or otherwise suitably fixed thereto the channel 13.

A traveler is arranged to travel in the channel 13 and is so connected to the window that the path of the window is determined as a straight line path. The traveler will now be described. The lower window sash channel 4 has spot welded or otherwise suitably fixed thereto the plate 14 having a flanged edge 15. The plate 14 carries the pins 16 upon which are rotatably mounted the rollers 17. By referring to Figures 3 and 5 it will be noted that the rollers 17 have their axes offset from the longitudinal center line of the channel guide 13. The rollers 17 are of less diameter than the width of the channel guide, hence, each roller engages but one side as at 18 of the channel guide 13 and has a clearance with the other side of the channel guide as at 19. This arrangement permits the rollers to have a true rolling, rather than a sliding engagement in the channel 13. The rollers 17 are so arranged that those having their axes in alignment on one side of. the longitudinal axis of the channel, in this instance two, have a rolling engagement with one side of the channel guide and the others likewise aligned on the other side of the longitudinal axis of the channel have a rolling engagement with the other side of the channel guide. Thus by this arrangement the traveler cannot cock or turn in the channel guide, and owing to its rigid attachment to the lower window sash channel, necessarily makes the window travel in a rectilinear path. The depth of the channel 13 is gauged relative to the rollers 1'1 so that there will be a nice or slightly pressed spring fit and consequently rattles eliminated.

The bottom 20 of the window well carries a socket member 21 for receiving the lower end of the channel 13. Since the guiding device here shown for descriptive purposes is combined with a window adapted to slide in a pair of parallel inclined channels, therefore the channel member 13 is adapted to be positioned inthe window well at an angle to the vertical and parallel to the guide channels 3. This specific form of socket comprises a single piece of metal which is turned back upon itself to form a U-shaped socket having the inclined surface 23 and the inclined surface 24 and a pair of ears 25 which are turned outwardly as at 26. Suitable securing means such as the bolts 27 are passed through the out-turned ears 26 to secure the.

socket to the window well. The socket is provided with a spring 28 which serves as an antirattler and support between the lower end of the channel 13 and the socket.

It will be noted that the channel member 13 can be mounted in the window well at almost any time during assembly and can be easily removed at any time after the body has been completely assembled and upholstered. The channel can be assembled in the window well before or after the interior of the body is trimmed and either before or after the window has been mounted within the channel guides 3. Assuming that the window has been mounted in the channel guides 3, the channel 13 is very easily inserted in the window well. This assembly may be accomplished by sliding the channel 13 over the rollers 17 and then downwardly toward the bottom of the window well. When the lower end of the channel reaches the socket21, the inclined guide surfaces 23 and 24 will guide the same into the socket and the spring 28 will hold the lower end of the channel yieldably against one side of the socket to prevent rattling. After the lower end of the channel has been inserted in the socket 21, the flange 12 of the triangular support plate 11 will rest upon the upper surface of the lock' board 10 and can be secured thereto by any suitable means such as the screws 29. The guide 18 and the glass run channels 3 can be properly aligned in parallelism by shimming the support plate at either end of the flange 12. Figure 13 shows the guide channel aligned with the glass run channels by shims 22 which are inserted between one end of the flange 12 and the lock board 10. I

In Figures 8 to 12 there is shown a modified form of traveler and channel guide socket. Instead of the rollers 17 for traveling up and down in the guide channel 13, as the window is raised and lowered, it is proposed to mount a slide member upon the plate 14. The plate 14 is adapted to have mounted thereupon a slide member such as the die cast slide 30. The die cast slide 30 is provided with a plurality of lugs 31 which are passed through openings 32 in the plate 14 and then riveted over to secure the slide 30 to the plate14.. The slide 30 is adapted to have a tight sliding fit within the channel 13 so as to hold the window in a'predetermined rectilinear course parallel to the ,channel guides 3 to prevent binding or cooking of the window in the guides. It will be noted that the guide member 30 is relatively long with spaced contact surfaces 90 near the opposed ends which contact with the guide channel on relatively small friction areas. The spacing of the contact areas prevents binding if the channel is not absolutely straight due to manufacturing variations. This also allows a closer fit to be made with a corresponding reduction in edge motion of-the glass. The inner faces of the channel guide 13 which contact with the traveler and guide the same are plane surfaces, and the guide surfaces formed by the upstanding lips 50 of the channel which engage the peripheral faces of the rollers 17, or the side faces of the slide 30, are parallel. Thus, the traveler must necessarily traverse 'a rectilinear path.

To insure an easy sliding engagement between the channel and the guide member 30 it is proposed to properly lubricate the slide 30. To this end the plate 14 is depressed as at 33, which depression cooperates with the slide member 30 to form suitable sockets for the reception of the opposed ends 34 of a lubricating wick 35. This lubricating wick can be made of anysuitable lubricant retaining material such as felt. Hence, as the slide 30 moves back and forth in the channel 13; the wiping action of the wick 35 lubricates the channel. To further insure easy and quiet movement of the slide 30 in the channel 13, the die cast member is provided with suitable openings for the inserts 36. These inserts are preferably of any suitable lubricant retaining material such as felt, but they can also becork. The felt inserts 36 tend to take upany play between the slide 30 and the channel guide and thereby prevent rattling.

The channel 13 is also provided with the leaf spring 3'7 which is positioned between the channel and the lock board and tends to take up any play between the same.

The -modified form of socket takes the form of a stamping having a pair of support cars 40 and a flange 41. The ears 40 and'the flange 41 are adapted to receive therebetween the support member 42 located in the bottom of the window well. The socket may be securedto the support member 20 by the screws 43 which pass through the flange 41. A rounded inclined guide surface 44 is pressed from the stamping. A rubber block 45 is secured to the socket member by means of the up-turned end 46 and the struck out lug 47. The rubber stop member is provided with an inclined face 48. The rubber stop member serves a two-fold purpose; namely, that of cushioning and arresting the downward movement of the plate 14 and necessarily the downward movement of the window, and also as an anti-rattler to yieldably retain the lower end of the channel 13 within the opening provided therefor in the socket member. When the channel is inserted in the socket member, the inclined surface 44 will guide the channel into the opening provided therefor in the stamped socket member. The inclined face 48 of the stop 45 likewise serves to guide the channel into its receiving opening. The inclined surface 44 and the socket opening are so positioned relative to the stop 45 that as the channel is forced into the socket opening by the inclined face 44, the rubber stop 45 will be compressed to yieldably and tightly hold the lower end of the channel in the socket opening to prevent the same from rattling.

Inasmuch as the guide device above set forth,

frigidly guides the window in a straight line path and prevents the same from tilting and moving edgewise in its normalplane, it is proposed to provide a novel runway for the window. This novel runway is shown in Figure 1'7. The body pillar 51 is covered on the outside in the usual fashion by' the body panel 52. The panel 52 is flanged inwardly at 53. The flange 53 is provided with a vertical longitudinal groove 54, the

opening of which is constricted as at 55 for securing therein the Weatherstrip 56. The weatherstrip 56 is preferably felt covered rubber but in opposed spaced relation to the flange 53 of the outer panel. The garnish moulding has a vertical longitudinal groove 58 which likewise has a constricted opening for containing therein the Weatherstrip 59 which is arranged to slidably engage the inner face of the window 2. Hence, it will be noted that the vertical edge 60 of the window from the inner face 61 of the pillar 51 and therefore is not guided. Inasmuch as the window 2 can not tilt owing to its rigid connection with the guide there is no necessity for guiding the vertical edge 60 of the window. Further where the window guide plate 14 is spot welded or otherwise rigidly connected to the lower window sash 4, as shown in Figure 6, the

primary function of the felt strips56 and.59 is that of sealing the window against the weather because the window in such a case is held not only against edgewise movement in its plane but also prevented from tilting in and out of its normal plane, that is, back and forth in the channel between the outer panel 52 and the garnish moulding 57. The normal plane of the 1 window is the plane in which it stands or funcclose the window form of the window guide and the attachment of the same to the window. In this form of the device the channel guide 13 and the traveler, which may be either the die-cast slide or the roller type, are the same as above described. The lower window channel 4 has secured thereto the channel member 65. The channel member 65 has the lower lip 66 and the upper lip 67. The upper lip may be spot welded to the channel 4. Instead of the plate 14 shown in Figure 10 and described above, the die-cast slide 30, in this instance, carries and has fixed thereto the plate 68. The plate 68 has the transverse slot 69, the outer end of which is enlarged as at 70. The slot 69 is adapted to receive the lifting stud '71 at the outer end of the regulator arm 8, and serves as a guide iorthe same when the window is raised and lowered by the regulator. The plate 68 is flanged outwardly as at 72 and upwardly as'at '73, to form a seat for the channel 65. The plate 68 also has struck upwardly therefrom the tongues 74, which cooperate with the flanges 72 and 73 to form an interlocking socket for the channel member 65. Hence, the plate 68 serves a two-fold purpose, that of interconnecting the traveler with the window and that of interconnecting the regulator and the window.

This detachable interconnection between the window and the plate 68 permits the window to be disengaged from the regulator and the guide very simply. To accomplish this, the garnish moulding 75 is removed from about the inside of the window opening and the window after first being raised to a position somewhat below its fully raised position is then tilted outwardly and simultaneously lifted as shown in Figure 16, whereupon the channel 65 can be disengaged from the socket formed by the tongues 74 and the flanges 72 and '13 of the plate 68.

In Figure21 there is shown a sectional view of a door. Since it is also an object of this invention to produce a window assembly wherein the window can be assembled from the side of the window opening rather than from the belt to this end as shown in Figure 21, the door pillar 100 is provided with a lengthwise slot 101 extending from the top of the window opening to slightly below the belt line. The window well has mounted therein the type of window guide shown in Figures 14 to 17, and generally designated 102. With this type 01' window guide it will be seen that the window glass 2 can be passed edgewise through the slot 101 and between the weather- strip 56 and 59 so that the channel 65 is slid into interlocking relation with the socket '73, 74, thereupon the slot 101 is covered by a suitable coverplate 103.

In Figures 18 to 20 the window guide is shown in combination with the rear quarter window glass of a convertible type of body. In this case the window glass 83 is guided below the belt in the felt coveredrubber channel runway 84, which channel runway is inset in the door pillar 85. The term belt line as used herein, is the dividing line extending horizontally midway between the top and bottom of the vehicle body and is usually coincidental with or slightly below the bottom of the window opening. As shown in Figures 19 and 20, the window 83 is guided below the belt but is unguided above the belt. Above the belt, as shown in Figure 19, the window is provided'with any suitable weatherseal, such as the rubber seal 86.

The window sash at thefore edge is provided with a sash extension 8'7 which assists in supporting the window in a vertical position when the window is raised. Inasmuch -as it is desirable to permit the window to be lowered as tar as possible, and since the rear wheel housing 82 must be accommodated in this type of body, the rear side of the window is only slightly guided below the belt when in raised position. Hence, as shown in Figure 18, the window can be lowered until the lower edge of the window is substantially in abutting relation with the wheel-housing. It will be noted that the sash extension 87, when the window is in lowered position, extends into the window well beneath the upper level of the rear wheel housing 82. In this type of window assembly the traveler is always rigidly connected to the lower sash and in conjunction with the channel guide 13 serves to rigidly hold the window, when in raised position, not only against edgewise movement in its own plane, but likewise against movement in and out its normal plane. This is particularly important because the one side of the window, when in raised position, is not securely guided below the belt and the other side is guided only by the sash extension 87 which is insufiicient alone to hold the window rigid in its raised position. It is, of course, appreciated that when the top is lowered with the window in raised position, the window 83 is unsupported above the belt and therefore, is held in .a. vertical upright position solely by the traveler and channel guide in conjunction with the sash extension 87.

From the above description it is evident that there is here produced a guide device for a window which will at all times rigidly maintain the window in a straight-line course whether the same be inclined or vertical, and regardless whether the lifting force is applied oil-center or-centrally of the window glass, and which guide device is easily assembled or disassembled within the window well.
